and resident ofA 'Wheeling county of Bhim and State of West Virginia, have i'nvegited certain" new and useful 'Im rovemente in )vhich'theollowing'is a specification. "Thisjinventien relates broadly to flights controlling devices, and more particularly to en enti-glere attach-ment for the headlights ovehieles.

The primary' objeetof the invention'iso provide asimple and inexpensive etteohment for the headlights ofvautomobiles .and other vehicles-which, while providing for the projeotion of light in e forward direction 'in sufficient volume to afford 'adequate road illumination to x-considerable distance in advance of the canso breaks up or modies the diree'tion of' reflected rays emanating from die lempthatthe latter are rendered 'unobtrusive to pedestrians end others inthe roadway.

A further object is to provide a device of the"cha,rneter mentioned by means of Whiehlarge'portionof the rays Erofteebed orw'ard from the reflector of the are deflected insueh manner that they cross in the .eenter line of projection, resulting in dedening'r vor subduing the brilliancy of the v direct ntrally'projeeted rays to an extent V whiclrelminetes 'thedozzling glare.

- with theimfention applied thereto; and

Eig. 4 is an enlarged detail section on the line 4 4, Fig. 3.

The device composing the' invention is taken Stamped from a sin le sheet/metal blank andeomprises a. ereu arrim 1 adapted for mwntingwthin e headllgh in Snif-ble P0- 'rccetioifqetters huist. sppucaemmeanovember 2,-1ai7l serein-mensf .y lly described, reference be? sitibn, eferebly adjacent the rear ieee Bof-the eadlight gles'sf2, seid rim hevin a yplurality of outwardly --directed ra ial tongues`3 adapted l to 'be bent or turned back inte seated elemp'in rele'ton to the exterior Slirfce of the u'sue conical reflector 4 -emgloye'd in headlight structures, as 'shown in i 3 'and e1..v A smell'ringflkeymember is ormed in a concentrie position, or in the 'line ofthe direct 'horizontelirays emanating 'from the le'mp 6, seid ring defining e' central Located above' As`aid=ringdihje member 5 and' preferably occupying theentire Spare ,Circular Opening 12through which seid rays 1 may pass lunobstruo'tedly.A v f betweenfsaid member 4andthe uppermost portion of 'the-rim 1;-is a series of parallel orizontally-disposjed 'narrow penelsor louvers 7 which lare struck up from the metal of the blank and areztu'rned back toform f leflectors. Said louyers' 7'-extend across from side tosde 'ofi-'said rim and have their ends connected to the'la'tter by relatively narrow?` unsevered lportions or ties 8` whichj are twisted more or less inbendin'g se1d'lou vers back to their inelined positions. Said louvers may be disposed aif'a suitable unform angle to the rim "1,5but are preferbly arranged at varyinginclinations in which the angles successive] f increase from the lowermost louver to t e uppermost louver,

which latter-'may bedisposed in e horizontal position as shown in Fig. 1. Asis obvious, the arrangement last rilentionedfprovides for the unobstructed pessagein e forward direction ofthe* major portion of the rays directed forward from the enzr'emevup er portion of the headlight ands to de ect 1n' e downward direction a considerable end-irwreesing' proportion. of the reysi'asthe upper central 'portion of the heedlightisiapproached by said lonvers.

A'phzrality of rela/tively shortllouvers 9 `of varying lengths is arranged in two series,

one attach of t e two-opposite sides of the member 5, seid ouvers being disposed vertically' and connected at their upper endstof the lowermost of the louvers 7 by means' of uncut portions o r ties 10 similar tothe ties 8, endV having tuur lower ends connected 1 n like manner 'to the rim 1; Said louvers are inclined rearward and outward, or in a direction away from the center of the device, to constitute deflectors whereby .a lar e portion of the rays-directed forward. are eflected in lateral directions crossing an imaginary vertical plane located inl a .central position in front of the headlight 1' Interposed between the lower portion of the central member 5 and the lowerxn'ost poi'- tion of the rim 1 and extending from the ,itically unobstructed manner, and. alsoto deinnermost of one series 4Aof louvers 9 tothe innermostofthe other is aseries'of horizon-l tally disposed louvers 11 whichareinclined rearward and upward.
